About this network

AS-PNAPOSK is operated by PacketFabric (Japan) Co., Ltd., a regional network service provider in Japan.

What it's used for

• The address space carries legacy netnames including kanzaki-CATV-CIDR-BLK-JP, INAKER-NET-CIDR-BLK-JP, and InternapJapanOsaka-CIDR-BLK-JP, indicating a mix of historical cable TV, enterprise, and data center allocations.
• With 13,312 IPv4 addresses announced across 6 prefixes and only 6 observed neighbours, the ratio suggests a role focused on transit or interconnection rather than large-scale residential access.

Notable

• All registrants are listed as Japan Network Information Center; IRT-JPNIC-JP, which is the national registry for Japan, rather than the current operator, reflecting the centralized allocation model of JPNIC.
• The operator was formerly known as PacketFabric Co., Ltd., as indicated by its web presence describing the name change.
• The inventory consists of six distinct IPv4 prefixes ranging from /20 to /22 blocks and a single /32 IPv6 prefix, representing a modest and segmented address estate.
